RADIATOR FOR AUTOMOBILES.

Specification of Letters Patent. Patented June 5, 1917.

Application filed March 16, 1916. Serial N o. 84,586.

Tol all whom t may concern.: Be it known that I, ISRAEL SlLvEn, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a`new and Improved Radiator for Automobiles, of which the following is a full, clear, and exact description.

This invention relates to radiator con structions and particularly to an improved construction especially adapted for use on automobiles and other places where water or other cooling medium is to be quickly cooled, and has for an object the provision of an improved simple and strong construction which provides for a minimum number of places where the parts are to be connected together.

Another object in view is to provide a radiator in which the soldering of oints has been eliminated by reason of the construction and arrangement of water carrying members.

A further object in view is to provide a plurality of independent water carrying members and spacing members formed independently of the water carrying members but connected therewith so as to act as heat radiating tins.

In the accompanying drawings Figure 1 is a front view of part of a radiator constructed according to the present invention.

Fig. 2 is a fragmentary horizontal section through one of the elements and spacing members embodying certain features of the invention.

Fig. 3 is a view similar to Fig. 2 except that it merely shows one end of a plurality of units embodying the invention.

Fig. 4 is a fragmentary perspective view of one end of the unit shown in Fig. 2.

In constructing radiators for automobiles and the like passageways must be provided for allowing thin sheets of Water to pass from the to to the bottom or vice versa, and in addition, openings between the sheets of Water must be provided for proper radiation of the heat. In order to help dissipate the heat there is usually provided a fan for sucking air through the air spaces in the radiator. In radiators heretofore the sheets of metal used in providing the water spaces have been variously constructed and the ends soldered so as to make a tight joint at the front and rear. As long as this tight joint or seam4 is maintained the radiator acts properly, but in case of a leakage it is very diicult to resolder the part that is leaking. In constructing the devicev embodying the present invention units are provided which need not be soldered and which are formed at one edge with a double seam so that in case the radiator becomes bent or injured by a collision or otherwise the water passages will be maintained unless the injury is enough to rip the metal apart.

Referring to the accompanying drawings by numerals, 1 indicates the usual frame for a lradiator and 2 and 3 the headers. For instance, water entering the header 2 from the engine passes from thence through the vari.- ous passageways 4 in the units 5 down to the header 3, from which it passes back to the engine or is disposed of in some other way. As shown in Fig. 1 the units 5 are spaced apart by heat radiating ns so that air passing through the various openings 6 will readily carry off the heat. Each of the units 5 is made from a single piece of sheet metal 9 bent double and provided with what is known as a double seam 7, as shown in Fig. 2. The bent edge 8, if desired, may be arranged at the front and seam 7 at the rear, these edges being vertical so that the open ends of the unit provided by the piece of sheet metal 9 will be at the top and bottom whereby the water mayl'easily enter and pass from the unit. l

In order to properly space these units and to provide heat radiating fins, a strip of metal 10 is bent back and forth so as to provide a plurality of squared portions 11. As shown in Fig. 4, Vthese portions are squared but they could be made rounded or of other shapes provided the bottom 12 of one squared portion rests against one unit 5 and the bottom 13 of the opposite squared portion ll rests against the next adjacent unit 5. Preferably the bent strip of metal 10 is loosely placed against the units 5 but is fixed thereto by having a plurality of slots 14 arranged therein so that the U-shaped retaining member 15 may t over the front and rear edges of the units 5 and extend into the slots 14. If desired, some soldering may be done to hold the members 5 in place, which in turn hold the various strips 15 in place.` There is provided one strip 15 for each end of each of the units 5 so as to .Laia

hohl the spacing members or strips 10 in proper position.

It will be noted that the ends 8 of members 5 are rounded so that in the bending 0r forming of these members the metal is not fractured whereby these members may withstand the pressure of the water without any danger of breaking or leaking. The rounded ends 8 would not give the usual nice straight even appearance of the radiators now 1n common use, so the clamping member 15 is formed with sharply bent corners and with a flat outer surface which will give a nice even appearance to the front faceof the radiator as well as act as retaining means. If the material of which the members 15 is made cracks slightly along the edge this will not injure the same as it is not necessary to make these parts watertight.

What I claim is 1. In a radiator of the character described, an inlet header, an outlet header, a. plurality of 'conduit members, each of the conduit members having the open ends connected to said headers, spacing and retaining members arranged between successive conduits, said last mentioned members having slots at the ends, and clamping strips substantially U-shaped in cross section itting over the vertical edges of the conduits and projecting into said slots so as to hold the spacing members in position.

2. In a device of the character described,

an intake header and an outlet header, a plurality of conduits connecting said headers, each of said conduits being comparatively flat so as to allow only a thin sheet of water to pass, heat radiating members for spacing said conduits arranged between adjacent conduits, each of said last mentioned members beinglformed with slots on each side, and a strip substantially U-shaped in cross section fitting over the vertical edges of said conduits and into said slots so as to hold the heat radiating members in position.

3. In a radiator of the character described, an intake header, an outlet header, a plurality of conduits extending from one header to the other, spacing and heat radiating members arranged between successive conduits, each of said members being corrugated so that there will be portions resting against opposite conduits, the connecting web between said portions being slotted upon each edge, and a retaining strip or clamp substantially U-shaped in cro-ss section fitting over the edges of said conduits and into said slots for holding the heat radiating and spacing members in position.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.

ISRAEL SILVER.
